Seasonal Breakdown
Wait until after May 1 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 71.0°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 15; this is the best renovation window.
